Stellantis bulletin S2509000011 REV. A
Stellantis filed this with NHTSA as a service bulletin dated Feb 27, 2026, received Dec 17, 2025, about the engine — 2 documents under this number: S2509000011 and 1 more. It names 11 model years across Jeep and Chrysler (2023–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 11 model years this bulletin names have filed 385 complaints with NHTSA since 2015. 144 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
While driving at highway speed the vehicle flashed a vehicle and I’ll shut down sign. A red turtle flashed and the vehicle began to decelerate. Had to pull over to a less than safe sand shoulder. Had highway speed traffic directly behind me. Dealership pulled codes related to the transmission. No previous issues or sign thereof. 25k miles
2023 Chrysler Pacifica · Engine · filed with NHTSA Apr 3, 2025 · ODI 11652655
While driving my vehicle, the check engine light came on after driving for about 10 minutes. It remained on and I called the dealer and they said that I should bring the vehicle in to be checked. They looked at the check engine light and said it was probably because the gas cap was not on properly.
2026 Jeep Cherokee · Engine · filed with NHTSA Oct 22, 2026 · ODI 11773012
I was driving the vehicle as normal when all of a sudden a message appeared and the engine shut down. The message was "Stop Safely Vehicle Will Shut Off Soon". It brought my speed down to 10 mph and I had to pull off the side of the road. This is now the 3rd time it has happened.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis S2509000011 REV. A a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the S2509000011 REV. A repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does S2509000011 REV. A cover?
The manufacturer filed it against 11 model years across 2 brands (Jeep and Chrysler): 2026 Chrysler Pacifica, 2025 Chrysler Pacifica, 2024 Chrysler Pacifica, 2023 Chrysler Pacifica, 2026 Chrysler Voyager, 2025 Chrysler Voyager and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
